getting back to the topic, I'm really just trying to mix and match drum, bass, and guitar parts the way you can mix and match arp patterns in the motif. The stly vs. arp discussion really is not important to me since I'm only talking about rhythm patterns in the drum, bass and guitar. I think I've found the section in the manual that discusses this. Gee, this beast is powerful! I love it. You can even reorder the drum parts in event edit and create new fill patterns!
